| 摘 要： | 生物炭作为一种新型的土壤改良剂和吸附剂，近年来成为农业、环境、能源等领域的关注热点。生物炭是通过有机物质在缺氧的条件下热解形成的，不同的原料及生产条件都会对生物炭的性质产生影响。生物炭能够能够改良土壤，改善土壤的容重、总孔隙度和保水性，还可以调节土壤的酸碱度，增强土壤阳离子交换量（CEC），提高土壤养分。系统总结了生物炭生产方法、理化特性及其对土壤理化性质的影响，为优选生物炭、提升生物炭产品附加值、促进土壤改良提供理论支撑。

| Abstract: | Recently, biochar as a new soil conditioner and adsorbent has become a hot spot concerned in agriculture, environment, energy and other fields. Biochar is produced by organic matter pyrolysis in absence of oxygen. Different raw materials and production conditions will produce biochar properties. Biochar can improve soil fertility, bulk density, total porosity and water retention, and also can adjust soil pH, enhance soil cation exchange capacity (CEC), improve soil nutrients. This paper summarized biochar producing method, its physical and chemical properties and its effect on soil physical and chemical properties, thus provided theoretical support to optimize biochar, upgrade the added value of it products, and promote the soil improvement. |
